MEANS FOR CONVERTING MOTION AND HQUSING THEREFOR.

cation.

This invention relates to means for converting motion and housings therefor; and it has for its object to provide improved mechanism of this character which will be positive in action and relatively simple and inexpensive in construction.

Among its particular objects the invention pertains to the provision of means of the character described particularly adapted for making and breaking electrical circuits, and, furthermore, pertains to inclosing structure for the same constructed to positively and unfailingly maintain the connection of its parts and accommodate wiring elements of I varying dimensions.

In the drawings, Figure 1 is a longitudinal sectional view of a pendent electrical switch embodying the invention, the parts being shown in full lines. Fig. 2 is a similar View showing the working parts of the mechanism. Fig. 3 is a perspective view of a detail element of the construction. Fig. 4 is a similar view of another element of the construction. Fig. 5 is a detail transverse sectional view taken upon the line a a, Fig. 2, and looking in the direction of the appended arrow. Fig. 6 is a detail transverse sectional view of the housing of the mechanism, taken upon the line b b, Fig. 1. Fig. 7 is a view in elevation of the male member of the housing, and Fig. 8 is a similar view of the female member of the housing.

Corresponding parts in all the figures are denoted by the same reference characters.

Referring with particularity to the draw ings, A designates the improved means for Specifioation of Letters Patent.

spectively, the member 5 being arranged in teriorly of the'member'ti. 'lhe means A are included initially within-a cartridge or casing 7, which is slipped into the housing B and secured therein.

In the preferred formof construction and operative connection of parts and members the cartridge or shell 7 is box-shaped in form and provided with a centrally-disposed partition 15, at either side of which the push-.

buttons 8 and 9 are arranged to be capable of longitudinal play. 'lhe inner end 10 of the cartridge 7 fits against an insulating-partition 11, .which extends across the interior of the member 1 of the housing B and is. connected with said partition 1 1, as by the screw.

- (Indicated in dotted lines at 12 in 1* ig. 1.) Tlhe push-buttons Sand 9 are loosely connected by a centrally-pivoted lever 13, supported by a pin 14, passed through thepartition 15, the ends 16 of said lever fitting within chambers 17 in the push-buttons 8 and 9. Each of the push-buttons 8 and 9 is provided with a chamber 18 at its inner end portion, and

within each of said chambers 18 is loosely.

mounted a slidable casing 19, (shown in detail in Fig. 3,) each capable of lateral movement in either direction of motion of its respective push-button, said casings being arranged to project toward-each other as the push-buttonsS and9 are moved oppositely Within the cartridge 7. Each of thecasings 19 is provided with a wedge-shaped pointed nose 20, and said noses 20 play upon an oscillating element D, which is disposed between the push-buttons 8 and 9 and which has opposite unobstructed and preferably plane surface portions toreceive said noses 20, said casings being forced into engagement with said oscillating element D by coiled springs 21, one of which is mounted in each of the chambers 18 and-its respective open-ended casing 19.

The oscillating element D is mountedto turn on its axis when the casings 19 engage with the same at opposite sides of the element D and also at the opposite sides of said axis. To this end the element D is formed upon, included within, or connected with a shaft 22, having end bearings 23, mounted in the cartridge 7, the element. D being arranged between enlargements 22 of the shaft 22, which enlargements are arranged intermediate of the end bearings 23 and the element D.

The element D preferably consists of a relatively thin flat plate 24, preferably constructed of stamped sheet metal or .cast

ings 19 will not prevent the maintenance of its operative form and condition. The portions of said element D which the noses at any time are traversing are of corresponding formation, causing smooth and positive action of the device.

The element D carries fixed upon or rigidly connected with itself contact elements or terminals and 26, respectively, which are ary 1 ranged to contact and coact with other fixed terminals, of which one, 27, is illustrated in The provision of contact points or. terminals may be varied as desired to pro- Fig. 1.

duce the required circuit making and breaking results, such results being operatively obtained in the oscillation of the element 1) under actuation of the reciprocating push-buttons 8 and 9 and they casings 19, tensionally carried thereby.

The housing B, which incloses the cartridge 7 and the improved means A, consists of the two members 1 and 2, which arehollow vin formation, preferably of spun metal, and

- are-connected together by a female thread 28 upon the member 1 .and amale thread 29 upon the member 2.. Said members include within the thread formation locking means E,

. which, while permitting-ready attachment and detachment, positively temporarily connect the two members together, so as to prevent accidental disconnection. The preferred construction consists of a continuous or ex tended mutilation of the male thread 29, as

at 30, and a local mutilation of the inner turn of. the thread 28, as at 31. When the thread i 29 is screwed into the thread 28, the mutilations 30 of the formercoact with the mutilation 31 of the latter, so as to temporarily bind the two members 1 and 2 together in looking engagement. The member 2 is broken up in practice into a number of lateral faces 32,

and the member 1 is similarly broken up into a number of lateral faces 33, which may be brought into coincidence with the faces 32 by relativelyturning the two members 1 and 2 and locking the same in such coincidence by the locking means E. p

The bushing device 0, comprising. the two members 5 and 6, admits the circuit-wires 3 and 4 and provides for circuit-wires of varying dimenslons by pIOV1S1OI1 of the two members 5 and 6 of varying diameters. With the use ofcircuit-wires of relatively small dimension the inner member 5 is retained within the outer member 6, with which it has screw connection; but in the use of circuit-wires of larger dimension the inner member 5 is removed by unscrewing and the outer member 6 alone is used. But two of the members 5 and 6 are illustrated in the drawings; but it is within the province of the invention to provide as many of such members as may be desired to accommodate in snug and tight fit the range of circuit-wires met with in practice of the invention.

The operation, method ofuse, and advantages of the invention will be readily understoodby reference to the-foregoing descrip- ,tion, taken in connection with the drawings.

Pressure alternately applied to the push-buttons 8 and 9 causes opposite reclprocation of the same and resultant actuation of the element D by the casings 19, carriedrby said push-buttons. This actuation causes oscillation of said element D and movement of .thecontact-terminals 25 and 26 to make and -posite directions.

The provision of the multiple-membered bushing device 0 is of utility,which will be readily understood.

The: provision of the locking means E, combined with the thread construction comprising the mutilated threads 28 and 29, permits of a temporary positive interlocking relation,which is a desideratum in awide range of mechanisms and devices similar to that specifically illustrated and described.

The entire mechanism is compositeand es sentially self-contained and is positive inaction.

Having thus described my invention, I claim and desire to secure by. LettersPatent 1.
